This project involved replacing the existing chilled water plant of the Logan Health Medical Center to support the North addition to the main hospital. The scope included demo and replacement of existing chillers, cooling towers, and pumps. The new plant is designed to be 100% redundant and is designed in conjunction with the Phase 2 new clean steam generator and dispersion grid. One half of the plant will be on generator power, allowing for cooling during a power outage. The project also included mechanical chillers and an air handling unit located on the roof of the parking garage. Additional civil work included a concrete trench from the exterior equipment well to an oxygen tank, as well as relocating an existing exhaust fan.
The chiller replacement also included the following:
- Two (2) cooling towers provide redundancy, with each providing 1500 gpm.
- Two (2) new 450-ton centrifugal chillers with VFDs and with new dedicated primary (lead/lag) chilled and condenser water pumps.
- Daikin Applied outdoor high-efficiency Air Handling Unit.
